Effect of co-substitution of Mn and Al on thermoelectric properties of chromium disilicide
CrSi2 was earlier reported to be an interesting thermoelectric material for high temperature applications because of its high oxidation resistance and good mechanical properties. In order to enhance its figure of merit, Mn at Cr site and Al at Si site were substituted into CrSi2. Our results indicate that Cr1−x Mn x Si2−x Al x solid solutions exhibit significantly lower thermal conductivity and a higher figure of merit than CrSi2.
